WHATS THE CLAIM AND GIVE REASONS PLS HELP TY. Many students today bring chips, cookies, and other junk food for school snacks. Even though many students really enjoy the taste of junk food, junk food should not be allowed in schools. Junk food makes it harder for students to concentrate. Also, junk food causes many students to suffer unnecessary weight gain. Students should bring healthy snacks to school, such as veggies, fruit, or cheese.
